The voltage is stepped up before being transmitted from a power station through overhead power lines to the consumer in order to reduce power loss and make the overhead power lines lighter, less expensive to build.

Here is the explanation why voltage is stepped up before being transmitted from a power station through overhead power lines to the consumer:

Power loss is inversely proportional to the square of the current. This means that if we can reduce the current, we can also reduce the power loss.

The current is inversely proportional to the voltage. This means that if we increase the voltage, we can reduce the current.

Therefore, by increasing the voltage, we can reduce the power loss.

In addition, the higher the voltage, the smaller the cross-sectional area of the conductors needed to transmit the same amount of power. This makes the overhead power lines lighter and less expensive to build.

It is true that you will feel a gentle pulling sensation in the muscle being stretched when Static stretching is done by slowly moving a joint.

Static stretching is most likely the most well-known and time-honored method of stretching. This entails extending a muscle to its maximum length and then maintaining that position for at least 15 to 20 seconds.

With each stretch, the emphasis is frequently on focusing on a specific muscle group.

The necessary light intensity of the disk if the disk has mass 3.89 g and radius 2.40 cm is 6.483 x 10^12cd.

a. Given that:

I = P/A

= Force x Speed/Area

Gravitational force, F= GM1M2/r^2

F= ma, F= mg

I= mg x c/q

That is,

i= mass x gravitational acceleration x speed/area

Explanation:

A beat frequency of 2.11 Hz would be heard. When the train car with the moving tuba approaches the stationary tuba, the sound waves emitted by the moving tuba are compressed, resulting in a higher frequency. This phenomenon is known as the Doppler effect. The beat frequency heard is the difference between the frequencies of the two tubas.

Using the formula: beat frequency = |f1 - f2|, where f1 is the frequency of the moving tuba and f2 is the frequency of the stationary tuba, we can calculate the beat frequency.

Since both tubas are playing the same tone at 69 Hz, f1 = f2 = 69 Hz.

When the train car approaches the station at a speed of 13.8 m/s, the frequency of the moving tuba is higher due to the Doppler effect.

Using the formula: f1' = f1 (v + vs) / (v - vd), where f1' is the frequency observed by the stationary observer, v is the speed of sound, vs is the speed of the source (tuba), and vd is the speed of the observer (stationary tuba), we can find f1'.

v = 343 m/s (at room temperature)

vs = 13.8 m/s (towards the stationary tuba)

vd = 0 m/s (stationary)

f1' = 69 x (343 + 13.8) / (343 - 0.0) = 71.11 Hz

The beat frequency is then:

|69 - 71.11| = 2.11 Hz

Therefore, a beat frequency of 2.11 Hz would be heard.

In Equinox, the Sun is directly above the equitor making day and night equal in both hemispheres.

Answer: a

Explanation: :)

The spectrum observed from the Sun (or any star) would exhibit an absorption spectrum. This is because the outer gaseous atmosphere of the star absorbs specific wavelengths of light, resulting in dark absorption lines in the spectrum.

In the cooler, lower-density outer atmosphere, where white light from the star travels, some atoms or molecules in the atmosphere absorb photons with particular energy. In the spectrum, these absorptions show up as black lines at specific wavelengths. The specific set of absorption lines that each element or molecule generates results in a distinctive pattern that can be used to identify the elements that are present in the star's atmosphere.

The absorption spectrum offers insightful data on the chemical make-up and physical characteristics of the star. Astronomers can ascertain the elements present, their abundances, and other characteristics like the temperature, pressure, and velocity of the star's atmosphere by examining the absorption lines.

Answer: To calculate the magnitude of the force exerted by the ball on Tom Brady's foot, we can use the impulse-momentum theorem:

impulse = force × time

The impulse is equal to the change in momentum of the ball, which can be calculated using the following formula:

impulse = m × Δv

where m is the mass of the ball and Δv is the change in velocity of the ball.

In this case, the initial velocity of the ball is 0 m/s, and the final velocity is 43 m/s. Therefore, the change in velocity is:

Δv = 43 m/s - 0 m/s = 43 m/s

Substituting the values into the equation for impulse, we get:

impulse = m × Δv

impulse = 0.53 kg × 43 m/s

impulse = 22.79 N·s

Now, we can use the impulse-momentum theorem to find the magnitude of the force exerted by the ball on Tom Brady's foot:

impulse = force × time

22.79 N·s = force × 0.021 s

force = 22.79 N·s / 0.021 s

force = 1085.71 N

Therefore, the magnitude of the force exerted by the ball on Tom Brady's foot is approximately 1085.71 N.

The answer is: 1085.71 N.

The small paper clip means the less strength of an electromagnet. Whereas large paper clip means higher strength of an electromagnet.

The measure of the magnet's strength can be accounted by counting the number of paper clips your electromagnet can lift. A specific quantity of mass can only be picked up by each electromagnet that is produced. More light things and fewer heavier ones are picked up by the electromagnet.

An electromagnet's or solenoid's magnetic field strength is determined by the coil's length L, current flow rate (in amps), and number (N) of turns.

The amount of paper clips held grows with the number of spins. This indicates that as the coil's turns rise, so does the magnet's strength.

Since paperclips are not magnetic by nature, they cannot be chained together on their own. The paperclips can, however, be momentarily magnetic by employing a magnet. A paper clip's steel can be easily magnetic, but it quickly loses its magnetism.

The ball will be traveling at a speed of approximately 18.9 m/s when it strikes the sidewalk below.

What is Speed?

It is defined as the distance traveled per unit of time, usually expressed in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

The horizontal component of the velocity remains constant throughout the motion, and it is given by:

Vx = Vcosθ

where V is the initial velocity of the ball and θ is the angle of projection. In this case, V = 25 m/s and θ = 45°, so:

Vx = 25*cos(45°) = 17.68 m/s

The vertical component of the velocity changes due to the acceleration due to gravity (g = 9.8 m/s^2). At the highest point, the vertical component of the velocity becomes zero, and the ball starts falling downwards. The final velocity (v) of the ball just before hitting the ground can be calculated using the following equation:

v^2 = u^2 + 2as

where u is the initial velocity in the vertical direction, a is the acceleration due to gravity, s is the distance traveled in the vertical direction, and v is the final velocity.

Initially, the ball is at a height of 12.0 m above the ground, so s = 12.0 m. The initial velocity in the vertical direction (Vy) is given by:

Vy = Vsinθ

where V is the initial velocity of the ball and θ is the angle of projection. In this case, V = 25 m/s and θ = 45°, so:

Vy = 25*sin(45°) = 17.68 m/s

When the ball hits the ground, its final velocity in the vertical direction is zero. Therefore, we can write:

v^2 = u^2 + 2as

0 = (17.68)^2 + 2*(-9.8)*12.0 - final velocity^2

final velocity = 18.9 m/s (approx)

Therefore, the ball will be traveling at a speed of approximately 18.9 m/s when it strikes the sidewalk below.

to find the modulus of elasticity MoE at 23% of moisture content based on the already given modulus of elasticity of 12% moisture content we need to consider a shrinkage behavior of material. the expected MoE comes out to be approximately \(6,836 N/mm².\)

given information:

Modulus of elasticity at 12% moisture content =7,920 N/mm²

resultant shrinkage or final shrinkage percentage FSP = 30%

To calculate the expected MoE at 23% moisture content we have the following equation:

MoE-23% =   \(MoE-12%\) \((1 - FSP (23 - 12) / (100 - 12))\)

MoE-23% = \(7,920 N/mm² × (1 - 0.30 × (23 - 12) / (100 - 12))\)

MoE-23% =\(7,920 N/mm² × (1 - 0.30 × 11 / 88)\)

MoE-23% = \(7,920 N/mm² × (1 - 0.1364)\)

MoE-23% = \(7,920 N/mm² × 0.8636\)

MoE-23% =  \(6,836 N/mm²\)
